Automation in Monitoring of Hydroponics for Tomato

Abstract

Nowadays, as the population is increasing widely, it becomes necessary for the cultivation of plants without the utilization of many land resources. There are different types of soil present on earth and different crops need different types of soils. Due to scarcity of water, it becomes difficult for the farmers to cultivate crops on land which requires a lot of water. With a hydroponic system in which the farmer has more control over plant growth, can get very high yields. In conventional methods, farmers need to monitor as well as manually control the parameters required for the efficient growth of the plants frequently. We have a sensing unit that senses various parameters like pH, Total Dissolved Salts (TDS), temperature, and humidity. The gathered information regarding these parameters is fed to the Arduino and monitored continuously. The Arduino is programmed such that whenever there is a change in these parameters from the optimum value, an alert message is sent to an android application installed in the smartphone.
